I am currently deciding on whether to up my compression, or buy a pumper carb. I did a search and came across this thread. My understanding is that a pumper carb is a very good update over the stock set-up. But how does it stack up powerwise to a compression increase from the factory 9.1:1 to say 10.5:1?? Since both updates will roughly cost the same, which one (or both?) should I consider first????? I already have a Hot Cam, Full Performance Exhaust, UNI Air filter, & Jetted stock carb. For the most performance-what is the next step?
